Color and size options
The five listed colors are Heather Slate, Heather Mauve, Athletic Heather, Heather Ice Blue, and White. Size availability differs by color: the current variants range from XS through 5XL overall, but not every size appears in every shade. Check the live size selector for the exact size and color combination you want.
The listing identifies solid colors as 100% cotton and heather colors as containing polyester. Its modern retail fit may feel different from an oversized shirt, so compare the size guide with a tee you already own before choosing.
